My new dog who I have only had for two weeks is a bit of a puker. He only does it in the middle of the night or early morning. He had had a crazy month (abandoned at park-adopted, back and forth between my place and my parents', neutering), so i think some of it is nerves or from his pain pills, but just wanted to get some input...

I will talk to his vet about Pepcid. He eats twice a day (Purina Pro Plan) and gets treats in the evening (People Crackers and soft chews). God love him, he doesn't like the fancy treats like Greenies or homemade Chicken treats

I hope this settles down for you. My dog has had stomach trouble ever since we adopted him. It would get better at times with food changes, but last year he developed obvious IBD. He's on a limited ingredient diet now, (duck and rice), and that seems to have settled him down for the time being and he has been off Flagyl since then.
